LIFTING-JACK.

Specification of Letters Patent.

Patented July 25, 1916.

Application filed April 27, 1916. Serial No. 94,045.

The present invention is directed to im pro vements in lifting jacksespecially adapted for use in connection with automobiles, and has forits object to provide a device of this character capable of beingreadily rolled under the axle to be raised and actuated in a simple andeasy manner to elevate the axle.

A further object of the invention is to provide a jack of this characterwhich is exceedingly simple in construction, durable, and one which canbe readily adjusted for use in connection with automobiles having theiraxles disposed at different elevations.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail reference will be had to theaccompanying drawing wherein like characters of reference denotecorresponding parts in the several views, and in which Figure 1 is a topplan view of the device; Fig. 2 is a side elevation of same; Fig. 3 is arear end view; Fig. 4: is a front elevation; Fig. 5 is a sectional viewon line 5-5 of Fig. 1; and Fig. 6 is a sectional view on line 6-.6 ofFig. 2.

Referring to the drawings 1 designates a frame which is formed fromtubular bars and consists of a main bar 2 one end of which beingprovided with a coupling 3 which has connected thereto a cross bar. 4:the outer ends of which being provided with couplings 5 which aredisposed vertically and have threaded in their upper ends tubular posts6, said posts being provided with diametrically arranged perforations 7the purpose of which will appear later.

A lifting frame 8 is provided and is U- shaped, and has supported by itsarms 9 axle engaging brackets 10. The arms 9 have their ends providedwith plugs 11 which are pivotally engaged between the furcations 12 ofthe rods 13, said rods being provided with vertically spacedperforations 14 which are adapted to register with the perforations 7formed in the posts 6, after which the pins 15 are passed through theregistered perforations to hold the rods in their adjusted positions.The other end of the main bar 2 is provided with a coupling 16, whichalso disposed vertically and has threaded in its upper end a post 17,said post being provided with a stub shaft 18 which is 'rotatablyengaged by the ratchet wheel 19. Cast integral with the wheel 19 is adrum 20 to which is fixed one end of the cable 21 the other end of whichbeing connected to the adjacent end of the lifting frame. 7 A hand lever22 is provided and is engaged on the bolt 23 which passes through thestub shaft 18, said lever having a pawl '24: carried thereby forengaging the teeth of the wheel 19, whereby when the lever is rockedrotary movement will be imparted to the drum 20 thus winding the cable21 thereon sufficiently to swing the frame 8 up wardly so that the axleengaged with the brackets 10 will be elevated as desired.

A spring pressed pawl 25 is supported by the post 17 and engages thewheel 19 to hold the same against accidental rotation, said pawl havingconnected to one end a cord 26 so that the pawl can be tripped after thelever 22 has been actuated sufficiently to permit the pawl 25 todisengage the wheel 19.

The couplings 5 and 16' are provided with caster wheels 27 whereby thedevice can be conveniently rolled from place to place and under the axleto be elevated.

What is claimed is A jack of the class described comprising a frameconsisting of a main bar, a cross bar carried by one end of the mainbar, tu-

, bular posts connected with the ends of the cross bar, rods adjustablymounted in the In testimony whereof, I afiix my signaposts, a. liftingframe pivotally connected to ture, in the presence of two Witnesses.
